Sierra Gonzales - Personal Trainer in Action

Movement is Medicine


"I help clients reach their fitness goals through science and evidence based training! Whether they want to lose weight, get stronger, or just live a healthier life, I strive to help my clients reach their goals!"

I grew up playing sports and once I graduated high school and was no longer playing sports, I knew I needed to find something else to keep me active. I decided to sign up for a gym membership, but I was terrified to actually start because I had never been in a gym and I had no idea what I was doing.


Slowly but surely I learned what to do and how to do things in the gym, but it took a long time. I eventually decided I wanted to help others learn how to work out and how to achieve their goals! I strive to teach my clients how to workout, and eventually how to program for themselves so they can be their own personal trainer because I know how scary and intimidating the gym can be!

"Sierra is just amazing. Not only does she ask you what your fitness goals are and cater the workouts accordingly. She’s a blast to be around. She kept me motivated in and out of the gym and made me fall in love with lifting."
